TO ALL WHOM IT MAY CONCERN:

Be it known that I, LEONARD TILTON, of Brooklyn, E. D., Kings county, New York, have invented a new and improved Mechanical Device for Transmitting Motion; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skill-ed in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates `to a new and improved mechanical device for transmitting a reciprocating motion from a rotary shaft; and it consists in the employment or use of a belt-shipper in connection with a earn, an idle and working pulley, and gearing, all arranged to operate as hereinafter set forth. In the accompanying sheet of drawings- Figure 1 is a side view of my invention.

Figure 2, a plan or top view of the saine.

Similar letters of reference indicate corresponding parts.

A represents the frame of the machine, which may be constructed in any proper manner to support the working parts, and B is a shaft placed horizontally in one end of thc frame, and having a toothed wheel, C, keyed upon one end of it, and a cam, D, keyed on the opposite end. This cam, in this instance, is composed of a spiral rib, c, on one side of a circular plate, b, as shown clearly in fig. 1, On the shaft B there is also keyed a toothed wheel, E, which gears into a pinion c, the latter gearing into a pinion, CX, at one side of a pulley, F, said pinion and pulley being in one piece, if desired, and placed loosely on a shaft, GX, in the frame A, and has a pinion, II, keyed on one end of it, which gears into the wheel O of shaft It. On the shaft GX there is also placed loosely a pulley, I, anda pulley, J, the latter bcingkeyed or otherwise secured on the shaft. K is a belt, which works around a pulley, L, on a driving-shaft, M, and around any of the pulleys F I J, on the shaft..G`/ And N N represent the two arms of a belt-shipper, the upper arinN being secured by a pivot-belt, d, on the fralnc A, and the lower arm N secured by apivot, e, to a cross-bar, f, in the frame A. The upper arm N is provided with a pendent-pin, g, which passes through an oblong slot, h, yin the lower arm N', and by this means motion is communicated from the upper to the lon'cr arm. The upper arm N is provided with a loop, z", through which the beltpasses, and the lower arm provided with a fork .j, between theprongs of which the belt passes, as shown in iig'. 1. O is a bent lever on the frame A, one end of' which is connected by a pivot, lc, to the upper arm N of the belt-shipper, the opposite end extending out beyond the frame A and passing between adjustable pins l? I on a bar, Q, which is fitted in guides Z Z, at one side of the frame A, and allonicd to slide freely therein. This bar Q has a friction-roller, It, attached to Aone end of it, and this roller works in the groove formed-by the spiral rib a, (see g. 1.)

The operation is as follows: As the shaft M is rotated, motion is communicated to the shaft B by means ot' the belt K running over the pulley F or J. The shaft I3 and cam D are turned in the direction indicated by the arrow 1, through the medium of the gearing II C, and the barv Q moved in the direction indicated by arrow 2, and when the belt K is working over the pulley F the shaft B is turned in a reverse-direction, as indicated by arrow 3, through the medium of the gearing 6X c E, and the bar Q moved in the direction indicated by the arrow 4. The belt K is shipped from the pulley F to the pulley J, and vice versa, by the. movement of the bar Q, the pins P P thereon acting against the lever O and moving the arms N N', the loose pulley I, serving to relieve the pulleys F J by causing the belt K to pass entirely off from one of said pulleys before it can act upon the other. e

This invention is applicable to various machines in which it is required to communicate a reciprocating movement to a certain part from a rotary drivine-shaftf I claim as new, as far as my invention is now perfected- The cam D and bar Q, in combination with the pulleys F I LI, gearing II O cX c E, belt II, and belt-shipper composed of the arms N N', arranged and operated automatically from the bar Q, substantially' in the manner as and for the purpose herein set forth.
